' citizen of the United States of America, re

siding at Detroit,- in 'the '.county of 'Wayne and State'zof Michigan,have invented 'certain 1 new and 'useful' Improvements in DriveMechanism4 for` Distributing-I'Vagons, of which the following-is aspecification, reference being had therein to the accompanyingdrawings.'

The invention relates tothe construction distributing wagons,'moreparticularl'y de.- signed for use in the distribution or spreal ingof manure 'over a field to be fertilized.' The inventionjconsist-'s inthe means em ployed .for driving the 'distribu ting mechanism, as'hereinafter set forth.

isnizand Fig.` 2 i's a `cross"sectiononline :zz-11s, Figi 1.'

Withwagons ofthetype above described,

it is usual; to provide a toothed'distrib'uting ofthe Wagon, and I also-means forfeeding the contents of the wagon, rearwardly int'o operativeproximity to' said Wheel at therear end distributing -vvheeLthismechanism being' driven from one of the Vground wheels.' -On the otherhand, 'when the" ivlagonis' used merely. to transport thelo'ad, thedistribut in'mechanism is 'out 0f action2 dt is thevparticular'object ofthe present/ invention to attain -a simple vconstruction of drive'connection 'between the. ground.

Wheels and the distributing agevchanis'ni, and

one 'which may be easily th n into o r-out 'of action by a slightmovement. This object is attained by the construction as follows:

A is' a side of gthe distributing wagon, B'

the rear axle, and C' the rear ground Wheel journaled thereon.'l l D isasprocket suitably connected to be' .driven from the ground WheelC, 'andE is the. (notshown) Which'is located at the rear end'of the Wagon shaftof the distributing Wheel body.

Theconnection'betvveen the sprocket'wheel .@-D- and the shaft Eislformed b a sprocket chai-n, and to secure the require shaft E two chainsare' preferably'em lo'yed in connection with" intermediate s ep-upsprockets. One of these sprocket chains F speed of the -extendsfrom asprocket Wheel G uponthe shaft E to a larger sprocket H, jand the' other-chain I extends from a sprocket J connected to Arotate with the'sprocket H toa sprocket K. The sprockets II, J, and K are'journaled in aframe 'comprising a pair of separated frame bars'- L, which, attheir'rear ends,` are pivoted upon the shaft E. The position ofthespi'ockets J and K is such that the' chain I ,extends across asegment of the annular ment of Said frame is in engagement with -sa1dsprocket.-

In order to produce an effective drivingengagement, and' t o distributethe stressto a desirable that the chain I should Wrap yabout. a segmentlof the' sprocket. On the other hand,t is e ually-desirablethat theengagement andt e disengagement of the chain should beeected with aslittle movement as possible to the frame L.l I have therefore devised aconstruction'in which the chain I,

when out'of engagement with thes'procket is held with portions of itslower half in angular moving the chain into or out of engagement D, whenthe frame Leis lowe'redf .The upper section of the `chainI ie alsopreferably supported b vfa'n intermediate rollA O, which is- ]ournaled-'n an upwardly extending'bracket 5P on the tion of `the parts, asillustrated in Fig.'4 1,-the chain I is held vvith'thev-portions Q..anthereof on opposite sides ofthe rolls'M f considerable "slightly spacedfrom the adjacentportions of the'A sprocket D.
